FAUCET.

Specification of Letters Patent.

Patented. July 27, 1915.

Application inea December 9, 1914. serial No. 876,218.

T0 all whom @'15 may concern Be it known that we, JEFFERSON C. Ross and GEORGE F. MCCULLY, citizens of the United States and the Dominion of Canada, respectively, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Faucets, of which the following is a specification.

This invention relates to a faucet for water or other liquid under pressure, and is designed to automatically close without shock under the pressure of the fluid pressure, and to be simple and direct in its action, and free from the complication of springs, etc., which are liable to derangement.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure 1 is a vertical longitudinal section. Fig. 2, a plan of the underside of the valve closing piston. Fig. 3, an elevation of the valve, and Fig. 4 is a section showing the valve of the faucet in the open position.

The body of the faucet is made up of two separate parts, a lower part 2 and an upper part 3. The lower part 2 is chambered from the upper end, as at 5, to receive a piston and valve 6, 17, to be described later, and has a threaded nipple 7 projecting from the lower end for attachment of the fitting, and for connection to it of the water service. The junction of the nipple to the body has a square portion 9 where it passes through the plate on which the fitting is mounted. |The bore of the nipple 7 is in connection with the chambering 5 through a restricted aper.

ture 8.

The upper part 3 of the body is screwjointed at 4. to the lower part, and is bored, as at 10, in axial alinement with the chambering 5 of the lower part and this bore 10 is in communication with a delivery pipe 11 connected to the upper part. The lower end of 3, where it projects within the chamber 5, has a seat 16 projecting downward from the edge of its bore 10. i

An operating stem 12, having a reduced lower end, passes gland-packed through the upper end of 3 in axial alinement with its bore 10, and outside the valve body is pinconnected at 13 to a handle lever 14V which is fulcrumed at 15 to a projection from the limit of its movement projects beyond the seat 16 of this end.

A hollow piston 6 slidably fits within the chambering 5 of the lower part of the body, and has a valve 17 projecting upward from its lower end, which valve is designed at the upper limit of the pistons movement to seat on 16, and close passage through 10 to the delivery pipe.

Apertures 18 are provided through the lower end of the piston connecting the space above to the space below the piston, the area. of which apertures are materially less than the delivery aperture of the faucet.

When this faucet is connected to a water service, the pressure of the water acting on the area of the piston will move that piston upward, and the valve 17 will be closed upon its seat 16,;'which position is the normal position of the valve. When it is required to draw water from the faucet the handle lever 14 is pressed down and the end of the stem 12 presses the valve 17 olf its seat against the pressure on the piston 6 and permits the` water, which passes through the apertures 18 of the piston, to flow from the delivery pipe. As soon as the pressure on the handle lever is relieved,`the apertures 18 being less than the delivery outlet. the pressure on the underside of the piston moves that piston up and the valve 17 seats on 16 and stops the outward flow.

It will be noted that the apertures 18 and that part of the passage 10 adjacent the seat of the valve 17 are so far removed from the outlet delivery pipe that the water flows quietly therefrom, and also that the closure of the valve is effected gradually and without shock, so that the objectionable water hammer consequent on sudden check is not vention, we hereby declare that what we claim as new and desire to be protected in by Letters Patent, is:

A water faucet the body of which is constructed in two parts which are screw-connected together, one part having an inlet aperture which is adapted to be connected to the water service and has provision for attachment of the fitting to the plate on which it is adapted to be mounted, said part having also a cylindrical chamber in axial alinement with the body, which chamber is in communication with the Water service inlet through a restricted axial aperture, the other part of the body having an outlet aperture in axial alinement with the cylindrical chamber, which aperture is in communication with the delivery outlet of the valve, a piston endwise movable within the cylindrical chamber, said piston having a valve projection which at the upper limit of the pistons movement will seat on and close the outlet aperture, said piston having also apertures through it the area of which apertures is less than that of the delivery outlet of the faucet, and a stem movable axially through the upper part of the faucet body and projecting downward through it into engagement with the valve projection of the piston, and a handle lever pivotally mounted to the body of the faucet and pin-connected to the upper end of the stem.

In testimony whereof we aflix our signatures in presence of two witnesses.
